true
false
A skater goes up and down hill moves at a constant speed !
TRUE
FALSE
An object moves at a constant speed means it changes its speed as it moves .

force
speed
position
friction
A contact force that opposes the motion of an object 1
friction
force
motion
velocity
Smooth surfaces produce less friction !
true
false
An object's motion depends on all the forces that act together !
true
false
Amount of force does not mean the strength of force !1!
true
false
Equal forces cancel each other !!!
true
false
two teams are pulling a rope with unbalanced forces ! what will happen ?
the rope will move in the direction of the team pulling with greater force .
the rope will move in the direction of the team pulling with less force
the rope will not move

steel
iron
plastic
paper
The amount of friction between two objects depends on
their surfaces.
true
false
Magnets work because they have magnetic fields around them.
true
false
A north pole of a magnet and a south pole of another magnet are near each other !!what do you think will happen ?
the north pole will attract the south pole of the other magnet .
they will push away from each other
they have no effect on each other
Unlike poles will attract ( North vs South).
true
false
Like poles will repel ( North vs North).
true
false
A noncontact force that pulls objects toward one another.
friction
gravity
force
motion
states that all objects are pulled toward one another by gravity !
strength of force
balanced force
law of gravity
friction
Gravity is a force that can be overcome.
true
false

true
false
gravity is greater on moon than on Earth .
true
false
When the pull of gravity is weaker, the object’s weight is less !
true
false
The pull of gravity is less the farther you are from the Earth’s center.
true
false
Objects with more matter have more mass.
true
false
the pull of gravity is greater on objects with less mass.
true
false

true
false
Your weight on Earth and on the moon is the same, but your mass is different.
true
false
